Exhibit 5.1



                                                                January 30, 2002



Dice Inc.
3 Park Avenue
New York, NY 10016


Ladies and Gentlemen:

          We have acted as counsel to Dice Inc., a Delaware corporation (the
"Company"), in connection with the preparation and filing with the Securities
and Exchange Commission of the Registration Statement on Form S-8 (the
"Registration Statement") registering under the Securities Act of 1933, as
amended (the "Securities Act"), the issuance by the Company from time to time of
up to (1) 2,345,039 shares (the "Incentive Plan Shares") of the Company's common
stock, $0.01 par value per share (the "Common Stock"), upon exercise of options
and purchase rights granted to certain employees of the Company pursuant to the
Company's 1998 Stock Incentive Plan, as amended (the "Incentive Plan"); (2) up
to 97,391 shares of Common Stock (the "Melland Shares") upon exercise of options
(the "Melland Options") granted to Scot W. Melland pursuant to the employment
agreement between Dice Inc. (formerly known as EarthWeb Inc.) and Scot W.
Melland dated April 23, 2001; and (3) 422,561 shares (the "Purchase Plan Shares"
and, together with the Incentive Plan Shares and the Melland Shares, the
"Shares") of Common Stock upon exercise of options granted to certain employees
of the Company pursuant to the Company's 1998 Employee Stock Purchase Plan, as
amended (the "Purchase Plan").

          In so acting, we have examined originals (or copies certified or
otherwise identified to our satisfaction) of such corporate documents and
records of the Company, certificates of public officials and of officers of the
Company, and such other documents, records and papers as we have deemed relevant
in order to give the opinion hereinafter set forth. In this connection, we have
assumed the genuineness of signatures, the authenticity of all documents
submitted to us as originals and the conformity to authentic original documents
of all documents submitted to us as certified, conformed, facsimile or
photostatic copies. In addition, we have relied, to the extent that we deem such
reliance proper, upon such certificates of public officials and of officers of
the Company with respect to any facts material to our opinion that were not
independently established.

          Based upon and subject to the foregoing, we are of the opinion that
the Shares have been duly and validly authorized by the Company and, when issued
upon exercise of the options and purchase rights granted under the Incentive
Plan, exercise of the Melland Options and exercise of the options granted under
the Purchase Plan, as the case may be, and upon payment of the applicable
exercise price or purchase price, as the case may be, will be validly issued,
fully paid and non-assessable.

          We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement. In giving such consent, we do not hereby admit that we
are in the category of persons whose consent is required under Section 7 of the
Securities Act or the rules and regulations of the Securities and Exchange
Commission.






                                                     Very truly yours,

                                                     /s/ White & Case LLP
